| Comment | Synonymy partly after Denzer et al. 2020. |
| Etymology | Named after the (relatively) small (Greek ”micros”) spines on the neck and back on this and other species, and from Greek “lophos” = neck, hair tuft, tip (or mountain top), apparently referring to the (relatively small) dorsal spines, at least in females. |
